   ...SYNOPSIS...
   THE DEEP MID LEVEL TROUGH OVER THE MIDDLE AND UPPER MS VALLEY IS IN
   THE PROCESS OF EVOLVING INTO A CLOSED LOW EARLY THIS MORNING...AND
   THIS LOW WILL DRIFT EWD OVER THE OH/TN VALLEYS TOMORROW.  AN
   EMBEDDED SHORTWAVE TROUGH NOW OVER ERN KS WILL MOVE AROUND THE LOW
   AND EJECT NEWD OVER THE CAROLINAS TOMORROW TO THE MID ATLANTIC
   TOMORROW NIGHT.  SURFACE CYCLOGENESIS IS EXPECTED ACROSS THE
   PIEDMONT NWD INTO VA IN ASSOCIATION WITH THIS EJECTING SHORTWAVE
   TROUGH.  A FEW THUNDERSTORMS WILL AGAIN BE POSSIBLE WITHIN THE MID
   LEVEL COLD POOL IN CONJUNCTION WITH DAYTIME HEATING...THOUGH THE
   MORE FOCUSED THUNDERSTORM THREAT IS ANTICIPATED ACROSS ERN NC/SE VA
   DURING THE AFTERNOON/EVENING.
   
   FARTHER W...AN ERN PAC MID LEVEL TROUGH WILL MOVE INLAND OVER THE
   NRN ROCKIES...WHILE THE SRN PORTION OF THE TROUGH DEVELOPS INTO A
   CLOSED LOW OFF OF NRN BAJA.  GRADUALLY DESTABILIZATION IS EXPECTED
   BY TOMORROW AFTERNOON FROM THE ID AREA SSEWD TO THE FOUR CORNERS.  A
   FEW THUNDERSTORMS WILL BE POSSIBLE ALONG THE BAROCLINIC ZONE FROM
   NRN NV TO SW MT WHERE ASCENT AND WEAK INSTABILITY COINCIDE...WHILE
   MORE ISOLATED THUNDERSTORMS WILL BE POSSIBLE WITHIN A WEAK MOISTURE
   PLUME FROM NRN MEXICO NWD ACROSS THE FOUR CORNERS INTO UT.
   
   ...ERN NC/SE VA AREA...
   LOW-MID LEVEL DESTABILIZATION WILL OCCUR AS THE EMBEDDED SPEED MAX
   MOVES NEWD OVER THE CAROLINAS AND COLD MID LEVEL TEMPERATURES /-22
   TO -24 C AT 500 MB/ OVERSPREAD THIS AREA.  DAYTIME TEMPERATURES IN
   THE 60S WITH DEWPOINTS IN THE UPPER 40S TO LOWER 50S WILL YIELD
   MUCAPE VALUES OF 500-1000 J/KG...WITHIN AN ENVIRONMENT OF
   SUBSTANTIAL DEEP LAYER VERTICAL SHEAR ON THE CYCLONIC SIDE OF THE
   MID LEVEL JET. THUNDERSTORMS...IN THE FORM OF SHORT LINE SEGMENTS
   OR SUPERCELLS...WILL LIKELY DEVELOP BY MIDDAY ACROSS THE PIEDMONT OF
   SC/NC AND SPREAD NEWD DURING THE AFTERNOON.  LARGE HAIL AND A FEW
   DAMAGING GUSTS APPEAR TO BE THE MAIN SEVERE THREATS DURING THE
   AFTERNOON AND EVENING.
